Pet HealthWorks, a leader in science-backed supplements is introducing Good Fitness, a first-to-market dual-action supplement that helps dogs burn fat for energy while preserving lean muscle – supporting healthy weight and mobility at every life stage.

FORT LAUDERDALE, Fla., Oct. 12, 2026 /PRNewswire-PRWeb/ -- According to the U.S. Food and Drug Administration (FDA), over 59% of dogs in the United States are classified as overweight. Excess weight can accelerate functional aging, leading to metabolic decline, muscle atrophy, and diminished mobility, the FDA reports. This creates a compounding cycle: excess weight reduces activity, reduced activity accelerates muscle loss, and muscle loss further slows metabolism – making it harder for dogs to stay active as they age.

The pet care industry has always treated weight loss and joint mobility as separate issues. Good Fitness by Pet HealthWorks bridges this gap by offering one product for both metabolic efficiency and lean muscle strength. Good Fitness rounds out Pet HealthWorks' active-aging mobility lineup, alongside the clinically studied Antinol Plus joint supplement.

"Weight gain and muscle loss and are compounding factors in canine mobility," said Ofelia Silva, President of Pet HealthWorks. "Good Fitness utilizes clinically studied, branded ingredients to convert fat into energy while preserving lean muscle. Good Fitness supports long-term vitality, joint stability, and overall quality of life."

Ingredient Science and Manufacturing Standards

Formulated without heat, using a cold-extrusion process to preserve raw ingredient integrity and bioactivity, each Good Fitness soft chew features:

• myHMB® (beta-hydroxy-beta-methylbutyrate): A patented metabolite studied to slow muscle breakdown, support muscle repair, and build endurance.
• Carniking® (L-carnitine): A well-researched compound that converts stored fat into metabolic fuel and preserves lean tissue.
• Vitamin D3 (cholecalciferol): An essential micronutrient for optimal muscle function and skeletal health.

Pet HealthWorks, Inc. carries the Quality Seal of the National Animal Supplement Council (NASC), ensuring adherence to strict manufacturing compliance, quality control, and transparent labeling standards.

Good Fitness comes in peanut-butter-flavored soft chews, and is available on Amazon, Chewy, Antinol Plus online, and Pet HealthWorks' TikTok Shop.
